  • Paxton grew up in Ladner, a Vancouver, British Columbia suburb (about two hours from Seattle). He was a huge Ichiro Suzuki fan growing up, but as a lefthanded pitcher, the player he really watched was the Yankees' Andy Pettitte.
  • Leading up to the 2009 draft, Paxton was constantly being compared to Major League star pitcher Jeff Francis, who is also from British Columbia.

    "Both were straight-A students, with a passion and a great work ethic. They could go to an extra level no one could touch due to their desire and motivation. That's why they improved so quickly," said Ari Mellios, former North Delta Blue Jays coach, who had Francis from 1997-99 and Paxton from 2004-06 in the British Columbia Premier League.

    "Most kids in our league improve, maybe 5 to 10% one year to the next," Mellios said. (He also coached Justin Morneau.) "These two jumped 50%. James was like Jeff. You looked and thought: 'He'll be okay.' The next year it was: 'Wow, look at how fast he'd come.'"

  • In 2009, the Blue Jays chose Paxton in the supplemental portion of the first round of the draft, but James chose to return to the University of Kentucky for his senior year.

    Blue Jays team president Paul Beeston told a Toronto newspaper that he had negotiated directly with Paxton's adviser, Scott Boras, which would be a violation of NCAA rules. The Wildcats wouldn't allow Paxton to play until he submitted to an interview with the NCAA, and when he couldn't secure a temporary injunction in the Kentucky courts, he left the team and signed with the independent Grand Prairie AirHogs of the American Association, following the paths of several prominent pitchers in recent years, including Tanner Scheppers.

    Then, on March 4, 2011, Paxton finally signed with the Mariners for a bonus of $942,500. Scouts Brian Williams and Jesse Kapellusch signed James for the M's.

  • In the springs of both 2012 and 2013, the Baseball America Prospect Handbook rated Paxton as the 4th-best prospect in the Mariners organization. He was at #3 in the offseason before 2014 spring camps.

  • September 7, 2013: About 12 hours after learning his grandfather died in nearby Vancouver, British Columbia, Paxton won his Major League debut with an impressive six-inning outing.
  • North Delta general manager Larry Waddell, who coached Paxton, remembers a kid in peewee baseball whose curveball confounded not only opposing batters but his team’s catcher.

    “Our difficulty was finding kids who could catch him because he threw the ball so hard and with so much movement,” Waddell said. “He would throw two fastballs past batters for an 0-2 count and, typically, throw a big breaking curveball to get them out. But there were kids who figured this out and would just swing wildly and start running on the third pitch on the expectation the catcher wouldn’t be able to catch the ball. There were innings James struck out four or five kids.”

    “I think that his journey has made him very mentally tough,” Ted Paxton, a career counsellor, said of his son. “James sees whatever happens as the journey he needs to take. One of his greatest strengths is his ability to accept and move through adversity. He is just not allowing anything to deter him.”

    Ted often caught for James when his boy wanted to practice in Leslie Park, behind their home in Ladner. As James grew, his fastball got harder and his curveball sharper, and his dad more scarred.

    “Oh boy, I’ve got all sorts of shin ulcers and lost a couple of toenails,” Ted said. “It was brutal. I thought: Gee, if I want to live through this, I better put on some gear. My brother is an ump, so he lent me his steel-toed boots and shin pads and mask and what have you, and then I went out and caught for James. It was scary, but thrilling. I loved it.”

  • Growing up in Ladner, B.C., Paxton did not stand out on the diamond or the mound. In fact, he was cut from a local all-star team as a kid and could only watch as his friends got to play. That summer, with help from his dad, he went out and worked vigorously on his game to ensure he wouldn't be left out again.

    Slowly but surely he improved and soon thereafter he joined the North Delta Blue Jays in the B.C. Premier Baseball League, arguably the top youth league in the country. From there he was selected to play with Canada's junior national team and eventually earned a scholarship to the University of Kentucky.

    At Kentucky, he made even more progress, adding nearly 10 MPH to his fastball and establishing himself as a bona-fide pro prospect.

  • In 2009, Paxton was drafted by the Blue Jays in the first round (37th overall). However, Paxton did not sign with the Blue Jays. The NCAA ruled him ineligible because of his contact with agent Scott Boras.

    In 2010, after being ineligible to return to Kentucky, Paxton signed with the Grand Prairie AirHogs in the independent American Association.

  • July 2, 2016: Mike Zunino and James Paxton, who came up through the Minor Leagues to play in the Majors together, were reunited as a pitcher-catcher duo in the 12-6 win over the Orioles. "There's few guys that can actually work their way up [together]," Zunino said. "And to be able to be a pitcher and a catcher and be able to do that, it's been nice."

    Both drafted by the Mariners, Paxton signed in 2011, and Zunino in 2012. They've been up and down since and most recently spent the beginning of the season in Triple-A Tacoma, both working out the kinks before being recalled. Paxton came up on June 1, and Zunino got the call after Steve Clevenger fractured his hand.

    Zunino made his season debut, hitting a pair of home runs, including a two-run shot in his first at-bat. He also threw out Orioles shortstop Manny Machado attempting to steal second base. "We've been working together for a long time and kind of learning together," said Paxton, who earned his second win. "He knows me really well and knows what I'm working on, knows what I'm capable of. So it's just nice to have a guy back there to know what I'm thinking."

    Both have made changes to their game this season. Paxton has developed his secondary pitches and Zunino has learned how to be patient and take better at-bats. And that all started down in Tacoma.  "For me, it was his arm slot," Zunino said of Paxton's progress. "He really found that about halfway through April and he's just made great strides. Its still relatively new to him he's still finding some triggers and where to be consistent at but it's been incredible. His velo has come up. His off-speed stuff's been great. And he's pounding the strike zone."

    Paxton has continued to develop in the Majors, so Zunino had to adjust his pitch calling Saturday to incorporate the cutter, slider and changeup more. But the chemistry was still intact. "Once you get to build that relationship and they trust you, that's when it's seamless and [there's] not much shaking off, not much second guessing," Zunino said.

    And Paxton said he felt very confident with Zunino behind the plate. "I know that Z's going to block anything that I throw up there in the dirt," Paxton said. "He's such a great defensive catcher and he does a great job catching the ball back there and calling the game. I really enjoy having him back there." (M Lee - MLB.com - July 3, 2016)


  • June 2010: The Mariners drafted Paxton in the fourth round, out of the American Association.

  • Jan 13, 2017: Paxton and the Mariners avoided arbitration agreeing to a one-year deal worth $2.35 million
  • Paxton has an 89-94 mph sinking two-seamer and a 91-97 mph four-seam FASTBALL with good running and sinking action. (That is some kind of heat from a lefthander.) He also has an above average 78-81 mph CURVEBALL with a big 12-to-6 break to put hitters away. He has a fair CUTTER and a circle-CHANGEUP that gets him a lot of swings-and-misses when it is on.

    He is the rare power lefthander who combines high strikeout totals with above average groundball rates.

  • 2016 Season Pitch Usage: 4-seam Fastball: 59.7% of the time; Sinker 3.7% of the time; Change 8.2% of the time; Curve 13.1%; and Cutter 15.3% of the time.

  • James has a clean, almost effortless delivery that gives him good command. He has a free and easy, long-armed motion that works really well. He comes from right over the top. Hitters can see the ball, but it also is a difficult angle to the plate, giving him deception. He comes from a good downhill plane.

    But he has a long arm action in the back, bringing one veteran scout to say, "I am concerned about the arm action, both the angle of it and the length. I don’t think they lead to command, nor do I think that the arm action will allow him to learn an additional pitch, make adjustments, or command his fastball to both sides of the plate.”

    The scout went on to say that Paxton’s future may be as a lefty set-up man out of the bullpen. And that he likes James' big and imposing size and arm strength.

  • Paxton's velocity fluctuates because the long-limbed lefty can have trouble repeating his mechanics. He tightened up his delivery a lot late in 2013, which allowed him to pitch well when called up to Seattle in September.

  • He works both sides of the plate. And  he gets a lot of ground balls.
  • Paxton can become a #2 starter.
  • James exhibits very impressive poise. His expression never changes, whether he's struck out three hitters in a row, or if a hitter or two takes him deep.

  • As of August 2014, Paxton became only the fourth pitcher in the past 100 years to start his career 6-0. 

  • As of the start of the 2017 season, Paxton had a 18-15 career record, a 3.43 ERA having allowed 22 home runs and 276 hits in 286 innings.
